GLOD-CRUSIIER.

Application filed March 31, 1916.

To all whom it may concern:

Be it known that I, STEPHEN A. GooDsoN, a citizen of the United States, residing at St. Elmo, in the county of Fayette and State of Illinois, have invented certain new and useful Improvements in @lod-Crushers; and I do hereby declare the followingr to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a clod Crusher or clod pulverizing machine, and the primary object of the invention is to provide a device which will efficiently stir up clods in a plowed field, and pulverize them for forming a seed bed.

Another object of this invention is to provide a device as specified, which includes a supporting frame which rotatably supports a shaft upon which are mounted a plurality of toothed pulverizing wheels, and to provide a plurality of arcuate ngers, which curve downwardly rearwardly of and between the rotary pulverizing members, and further to provide meansfor adjusting the position of said downwardly extending arcuate fingers.

With the foregoing and other objects in view this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanyin drawings and claimed.

In descri ing the invention in detail reference will be had to the accompanying drawings wherein like characters designate like and corresponding parts throughout the several views, and in which Figure 1 is a bottom plan of the clod crusher, and Fig. 2 is a longitudinal section through the clod crusher.

Referring more particularly to the drawings, 1 designates the supporting structure of the clod pulverizing machine as an entirety, which has bearings 2 and 3 attached to the under surface thereof and arranged in pairs, for rotatably supporting axles 4 upon which are mounted supporting wheels 5. The supporting structure 1 has a box like structure 6 carried by its forward end, the upper portion of which is closed by a pivoted or hingedly mounted curved cover 7. A shaft 8 extends through the space within the curved cover 7 and is supported by suitable bearings 9 which are carried by the sup- Speccation of Letters Patent.

porting frame. The shaft 8 has balance wheels 10 mounted thereon, and it is operatively connected to the prime mover or gasolene motor indicated at 11, which is positioned within the box like structure 6.

rIhe shaft 8 has sprockets 12 and 13 mounted upon its outer ends and positioned laterally of the sides of the supporting frame l. Sprocket chains 14 and 15 travel about the sprockets 12 and 13 respectively and about sprockets 16 and 17 which are car-y ried by a shaft 18. The shaft 18 is rectangular shaped in cross section and has its ends 19 upon which the sprockets 16 and 17 are mounted reduced and round. The rounded ends 19 are seated in suitable bearings 20 carried by the supporting structure 1.

The shaft 19 has a plurality of rotary clod pulverizing or crushing members 2l mounted thereon, which rotary clod pulverizing members are provided with a plurality of radially extending relatively large teeth 22 which are spaced from each other at distances practically equal to their lsize, as clearly shown in Fig. 2 of the drawings. The rotary clod pulverizers 21 are spaced from each other along the length of the shaft 18.

A,plurality of stirring lingers 23 are pivotally connected as shown at 24 to the supporting frame l, and they extend rearwardly through a bar 25 and have their rear ends curved as shown at 26. The rear curved endsof the lingers 23 are positioned between the spaced rotary pulverizers 21 and their lower pointed ends 27 project below the r tary pulverizers as clearly shown in Fig. 2 of the drawings. The bar 25 is adjustably mounted between the supporting frame and it has an adjusting screw 28 connected thereto for raising or lowering the bar 25 and consequently regulatingl the position of the lingers 23. hingedly connected as shown at 30 to the supporting frame l and extends over the rotary pulverizers 21 and the fingers 23.

A seat 31 of the ordinary construction is supported by a suitable resilient or spring standard 32 above the supporting structure 1 and in close proximity to the adjusting screw or rod 28.

From the foregoing description taken in connection with the accompanying drawings, the advantages of construction and of the method of operation of the improved A hinged cover plate 29 isl clod Crusher will be readily apparent to those skilled in the art to which this invention appertains, and while in the foregoing description, the principle of the operation of this invention has been described together with various features of construction, it is to be understood that certain minor features of construction, combination and arrangement of parts may be altered to suit praetieal conditions provided such, alterations are comprehended within the scope of what is claimed.

What is claimed is 1. In' a clod pulverizing machine structure, the combination, of a portable supporting structure, a prime mover carried by said portable supporting structure, a rectangular' shaft rotatably supported at the rear end of said supporting structure and operatively connected to said prime mover, a plurality of rotary pulverizing members mounted upon said rectangular' shaft for rotation therewith, said rotary pulverizing members having a plurality of relatively large radiatingteeth formed upon their periphery, said rotary pulverizing members being spaced from each other, and stirring fingers carried by said supporting structure and extending downwardly between said rotary members.

2. ln a clod pulverizing machine structure, the combination, of a portable supporting frame, a rectangular shaft rotatably carried by the rear end of said supporting frame, a prime mover carried by said supporting frame, means operatively connecting said rectangular shaft of said prime mover for rotating the shaft upon operation of the prime mover, a plurality of rotary pulverizing members carried by said rectangular shaft and mounted in spaced relation to each other, a plurality of stirring lingers pivotally connected to said supporting structure and having their rear ends curved and extending downwardly between said rotary pulverizing members, and means for adjusting the position of said stirring fingers.

3. In a clod pulverizing machine structure, the combination, of a portable supporting frame, a prime mover carried by said supporting frame, a rectangular shaft rotatably supported at the rear end of said supporting structure, a plurality of rotary clod pulverizing members mounted upon said rectangular shaft in spaced relation to each other, a plurality of relatively large radiating teeth formed upon the peripherics of said rotary clod pulverizers, a bar adjustably suspended beneath said supporting structure, a plurality of stirring fingers pivotally connected to said supporting strueture and extending through said adjustable bar, said stirring fingers having their rear ends curved and extending downwardly between said spaced rotary elod pulverizing members, and means operatively connected to said bar for adjusting its position with respect to said supporting structure.

In testimony whereof I aiiix my signature in presence of two witnesses.
